So for one commercial, they could have the chocolate team try a running play, but as the runner tries to run around the side, he gets stuck in the peanut butter, and he gets smeared by the peanut butter, and the announcer says: "There goes chocolate, right around the outside, but he's gotten stuck by that peanut butter center! Hey: chocolate with a peanut butter center? Yum! That sounds delicious!" See what I mean here? And then they could have another commercial where the peanut butter quarterback gets sacked by the chocolate team, and the announcers says: "Peanut butter has chocolate all over him! And all the peanut butter receivers are covered by chocolate! And down he goes: peanut butter gets chocolate piled on top of him! But hey: that sounds delicious, doesn't it? Mmmm!" And both of these spots would show the animated graphic of the X's and O's like the real commercial, looking like an animated football playbook.
In the actual ad, which I can't show you, as I can't find it online (curses!), they show us a completed pass, and then say it's "the perfect combination", but they don't use that idea of getting the two things smashed together, like football so readily suggests. And they could also make plays on other football terms, like saying that peanut butter is in chocolate territory, or that peanut butter runs right through chocolate's outside line and gets smeared because he's covered so well by chocolate, etc. Or they could have a peanut team and a chocolate team, and say the peanuts get "creamed" after slipping through like butter, and getting piled on by chocolate. Anyway, there are so many fun ways they can go with this idea. I just like the idea a little better of one team tackling and smearing the other one to combine the two together, like in the famous old campaign where they have the two things literally crash together, because football so readily suggests such an approach.
